Ch -2 vs CH -1

Which will yield the best throughput, CH -2 at 10MHz with no interference from part 15 devices or CH -1 at 20MHz which will overlap CH 1 and CH 2 with the potential for interference from these channels? That's probably a hard question to answer since there will be situations of little to no interference from CH 1 and CH 2 to a lot of interference from these channels. I get this question a lot and I imagine that since this is conditioned on the environment of a particular node the only way to really answer it is to run tests on a node and then make the decision on which channel to use.

It depends

Hi Bob -

Like you stated, it really depends. So far I've found that a nice clear channel even at a lower bandwidth yields more effective throughput than a semi-busy channel with a wider bandwidth. You'll have to test this at your specific locations and see what works best. In general, I'd go with clear channels first and work out from there.
